Description

Increase performance in the valvetrain of your 1998.5-2018 Dodge 5.9L / 6.7L Diesel with the Hamilton Cams 07-S-003 Valve Springs. Stock springs have 78-82lbs of pressure seat pressure on average at 1.380". If you are over 50psi (boost or drive pressure) and 3,800 rpm, stock springs do not fully control the valvetrain. This allows a few negative things to happen. First, valve float, which can cause serious damage to the valvetrain. Second, intake and exhaust valves can be blown open by boost and exhaust drive pressure which allows reversion. Reversion can hurt your power potential by allowing exhaust gasses to enter the cylinder on the intake stroke. Inert gasses in the exhaust, when reintroduced into the cylinder shield the fuel particles from oxygen in the cylinder.

This does a few things that negatively affect power. It increases the time delay from start of injection to start of combustion, it decreases the maximum pressure and maximum temperature reached in the cylinder and it increases the total time needed to completely burn the available fuel. Correct valve spring pressure is a very important piece of power production. If you are running a tuner on an otherwise stock truck with a VGT charger, based on exhaust drive pressure, you need these.

Hamilton Cams suggests these springs if you are over 50lbs. of boost(or drive pressure) or over 3800 rpm or when running aftermarket camshafts. Hamilton has slightly lowered the pressure on this springs from 110# to 103#. If you are running over 4,500 rpm with a large cam, they suggest going with 103# springs with different processing for better longevity in extreme applications as well as their light-weight 4130 or titanium retainers. Retainers not included.

Features:
  • 103# Spring 
  • Complete Set
  • Works For Over 50lbs Of Boost

Does this product come as a complete set?

Answer
Yes, this is a complete set of valve springs.
Will these be ok for stock cam? Never plan on upgrading cam. But do plan on going over 50psi. Will also be purchasing upgraded push rods but wanted to make sure these won't ruin my stock cam. 1999 5.9. Didn't see a selection for lighter duty but still above stock.

Answer

The HAMILTON CAMS 07-S-003 VALVE SPRINGS would be a great option when running over 50 pounds of boost pressure. These valve springs do not require an aftermarket camshaft for installation.
